To all whom it may concern:

Be it lrnown that I, JOSEPH TV1-Irre, a citi een of the United States,residing at liscatw way township, State of New Jersey, (postoiliceaddress, Bound Brook, New Jersey), have invented certain new and usefullinpiovements in Sheet Registering and Gragiiig illechanisin; and l dodeclare the f ollowing to be a full, true, and exact descripn tion ofsaid invention, such as will enable others skilled in the art to whichit appertains to inale use of the same.

This invention relates to mechanism 'for positioning sheets in machinesfor operating on such sheets and particularly to devices for positioningsheets so that theywill be printed in accurate register in printingmachines. The devices which l have illustrated are intended to positionthe sheet lon-- gitudinally only, devices for positioning itlaterallybeing no `part of my present inven tion, and therefore, notshown. My novel :mechanism may be used in connection. with any form ofsheet handling deyices by which. sheets are presented to machines. i

ln niy present invention, have provided means by which sheets may bepresented to a sheet carrier with very great accuracy and hy simple andefficient mechanism, the carrier being either a part of the machine for`operating on the sheet or a device which may he readily attached to suchmachine. My novel devices include not only mechanism for accuratelypositioning thesheets against a gage, lout also devices by which Suchgages may be readily.adjusted and particularly `while the machine is inmotion.

ln the drawings, Figure 1` represents a side elevation of a rotarymachine in a more or less diagrammatic form, this machine heilig onewhich l have chosen for purposes of illustration to show the applicationof my novel devices. i

Fig. 2 is a side elevation of a portion of i my novel mechanism, some`of the parts heing brolren away.

Fig. 3 represents a partial end elevation of the mechanism of Fig. 2,looking in the direction of the arrow 3 in Fig. 2.

Fig. l is an enlarged perspective view of :i portion of my novelmechanism, showing particularly the devices for supporting and movingthe gage, the sheet wiper and the sheet guides.

The corresponding parts are referred to both in the drawings and thefollowing description by similar reference characters.

Referring now to Fig. 1, 9 represents the impression cylinder and 10 theform cylinder of the printing machine which I have chosen for purposesof illustration. The machine is provided with the usual inlringarrangement and a delivery mechanism below the impression cylinder 9.This nlring y and delivery mechanism being no part of my presentinvention, no detailed description thereof is necessary. l1 is a feedcylinder carrying a set of grippers 12 mounted on a shaft 13 andoperated by a cam lever and roller ruiming on a cam 1d, all in the usualmanner. These grippers 12 are shown at the feeding point of the cylinder11, and it will be understood that they close on a sheet presented atthis feeding point and carry it to the impression cylinder 9 to be takenby the usual set of sheet grippers on that cylinder. rlhe grippers 12strike against abutmeiits 15 carried by the shaft 16 mounted in thecylinder 11. lrepresents sheet supports extending substantially tangentto the cylinder 11 at the feeding point thereof, these supports beingmounted on brackets 18 attached to a fixed shaft 19 held in the 20represents side frames of the machine. a series of tape pulleysmountedon the shaft 2l, ruiming in the side frames of the machine. It will beunderstood that the tapes 20 carried hy' the pulleys 20lead from asource of supply for the sheets, usually a,

sheet separating device by which sheets are talren one by one from apile, and that any other suitable form of sheet support and forwardingdevice may be used. 22 repreu sent-s a roller mounted on an arm 23attachedr to a shaft 24 free to rotate in the side frames of themachine. The roller 22 is held in contact with the pulleys 20 by theaction of a cam 25 act-ing through a cam lever 26, link 2T and lever 28,tlielatter being fastened to the shaft 2li- The roller 22 is held awayfrom the pulley 20 by the spring29 acting on the shaft 211, as shownparticularly in Figs. 1 and 2. It will be understood that as many of therollers 22 as are necessary will be provided on the shaft 24.

80 is a shaft extending across the machine and free to rotate in theside frames thereof and carrying one or more sheet wipers 31 attachedthereto. This wiper may be of any suitable material, though preferablyof rubber, and While for most purposes, it could be a roller havingeither a Whole circumference or a circumference partly cut away, Iprefer to make it in the form shown, since, as Will be apparent, thesmall active portion of the Wiper which I have shown is sufficient.r)The shaft 30 has attaehedy to it a gear 32 meshing with a gear 33 onthe shaft of the feed cylinder 1l, this gear being larger than thecircumference of the feed cylinder ll and the gear 32 being smaller thanthe circle generated by the end of the Wiper 3l. This arrangement causesthe active end of the Wiper 3l to travel at a considerable faster speedthan the periphery of the cylinder ll.

34 is a gear loosely mounted on the shaft 19 and meshing with gears 32and 35, the latter being attached to the shaft 2l. This gear 35, in thedevice illustrated, is larger than the pulleys 2O in approximately thesame ratio that the gear 33 is larger than the cylinder l1, so that thepulleys 2G and the cylinder 11 have substantially the same surfacespeed.

As Willbe seen from an inspection of Fig. 2, the supportsl are mountedso as to lead a sheet from the tapes passing around the pulleys 20 tothe feeding point of the cylinder 1l.

36 is a sheet front gage of which one or more may be provided. Each ofthese gages is adjustably mounted on the end of an arm 37 and heldagainst vertical movement by a screvvr 36. The arm 37 is loosely mountedon theshaft`38 of the cylinder li. 39 is an arm attached to the shaft 38directly behind the arm 37. Between the arms 3'? and 39 is a` Wedge 40,WithV which the faces of arms 37 and 39 are arranged to cooperate. Asshown particularly in F ig. 3. a link el, surrounded by asm-ing 40 andprovided With a stop pin72, connects the Wedge el() Vwith a lever 42pivotally mounted on a bracket 43 attached to the cylinder 11. rl`hislever 42 carries a ball or roller ai, which is arranged yto contact withthe face of a cam a5 mounted on a rod Li6 in the side frame of themachine. The cam 45 is'also provided With a steady pin el? engaging withthe side frame. The end of the rod i6, outside of the `side frame, isscrew-threaded and mounted thereon is a nut 48 provided with Worm teeth`These teeth engage with a.

worm gear 49 attached to a shaft 50 mounted in brackets en the sideframe and extending longitudinally thereof. as shown particularly in Fig. l.V It will be understood that if the gage 36 is duplicated on the'opposite side of the machine, as will usually be the case, the mechanismjust described Will also be duplicated on that side of the machine, andsuch duplication is shown in Fig. l., in Which .the shaft 50 is shownextending to a point adjacent the delivery pile of the machine. On thisside of the inachine, the shaft 50 is broken at 5l, where :1 universaljoint is provided and the bracket 52 is slotted to permit verticalmotion lo the outer end of the shaft 50, such vertical motion beingprevented normally by the spring The outer end of the shaft 50 isprovided with a hand wheel and spiral gear 55 meshing vith a spiral gear5G mounted on a shaft 5T extending across the machine and 'havingmounted on its opposite end, a spiral gear similar to 5G, which in turnmeshes with a spiral gear similar lo gear 55 on the end. of the shaft5() on that side of the machine. The shaft 5T, on the side of themachine shown in F l, will preferably be provided with a hand wheel 58,similar to hand wheel As a means by which the operator muy readilydetermine the location of the gages '56, l provide a suitable indexingdevice for the shaft 50 which may be of any conveniemv type and locatedin any convenient place. is one form of such device, l have shown inFig. l on the shaft 50, a worm'whcel T3 which is engaged by a roller onthe end of lever T-l, pivoted on the side frame of the machine, theopposite end of the lever passing over the index '75. it is obvious thatthe iosition of the lever ifi in reference to the index Will indicate atany time the position of the gage on that side of the machine. rlf'heshaft 50 on the opposite side of the machine would be provided with asimilar indexing device. These indexing devices may also be placedadjacent the hand wheels and 58 in any convenient manner.

In the form of device illustrated. the gage 236 is mounted on a member5), which is held adjustable to the arm 3T by a screw l. the gage 36being vertically adjustable on the member 59, as shown particularly iuFig. l. and held by the screw 3G. rhe member 5i) has an extension Glprojecting over the inner end of the gage also as shown particularly inF ig. 4. The member 59 has another projection 60, whirh has a face lyingin the periphery of the cylinder' Ill. 'l'his member (30 constitutes anabutment with which the Wiper 3l coperates, for a purpose explainedhereafter.

In addition to the regular sheet gripperv l2, the shaft i3 is providedwith one or more sets of guiding fingers G2 loosely mounted on shaft 13in a manner more jmrticularly illustrated in Fig. G5 represents a memberattached to the shaft 13 and adjacent to :i projection 66 on the guide(l2. A spring is interposed between the member G5 and (the projection 6Gand a member GS forming part of the member G5 is provided to limit themotion of the end G6 of the guides (52. The. guides G2 are preferablyarranged to contact with the gage 36 and to extend beyond said gageadjacent the member GO, as shown parlilo llo

lll

ticularly in F ig. 4, and preferably two of these guides are provided oneither side of the path of operation of the wiper 31.

69 is an arm connected to the hub of the arm 37 and carrying a rod 70surrounded by a spring 71, the latter abutting against the arm 39.

The operation of my novel sheet positioning device is as follows: Thecylinders 9, and 11 and the connected mechanism being in motion, a sheetis carried by the tapes beneath the rollers 22, which at this time arein contact with the pulleys 20. T he sheet is forwarded by the contactbetween the pulleys 20 and the rollers 22 along the supports 17 to thefeeding point ot' the cylinder 11. its the grippers 12 approach thisfeeding point, they will have been opened by the cam 14 in the usualmanner and the gage 36 will be considerably removed Afrom the gripperabutments 15 by reason of the Afact that the wedge would have beenwithdrawn trom between the arms 37 and 39 by the spring 40, thuspermitting the spring 71 to move the arm 37 in relation to thecylinder,

toward the right oi Fig. 2. As th' gage 36 is carried toward the feedingpoint, the roller 44 will engage the cam 45 to thrust the wedge 40between the arms 37 and 39,

thus giving a motion to the gage 36 clock# wise ot the view in F ig. 2,or in a direction the reverse ot the motion of the periphery ot'cylinder 11. The amount of this motion will obviously be controlled bythe amount oi motion given the `roller 44 by the cam 45. This reversemotion oi the gage 36 occurs at the time when the Vhead of the sheetreaches the feeding point and comes into engagenient with the wiper 31and the wipereabutment 60. About the same time that the wiper 31 engagesthe sheet, the roller 22 is lil'ted theretrom to permit the wiper todraw the sheet ftorward at a greatly increased speed..

d ust prior to the engagement ci the sheet by the wiper 61, the shaft 13will have been turned so as to bring the grippers 12 and the guides 62down close to the gripper abutments 15', the members 60 and the gage3.6, Because ot the arrangement shown particulai-ly in Fig. 4, theguides 62 precede the iingers 12 and engage with the top oi the gage 36before the grippers 12 close on the sheet. An inspection ot Figs. 2 and4 will. `show that, in the preferred term, the members and the abutments15, on the one side, and the guides 62,`on the other side, torni a sheetguideway leading to the gage 86 and that the wiper 31 operates on thetill sheet held in this guideway. After the sheet has been pushed by thewiper 31 against the gage 36. the fingers 12 close thereon by reason otthe further rotation oi the shaft 13, this further rotation beingpermitted by the yielding of the spring 67. The "sheet now being engagedbetween the grippers 12 and the gripper abutment, the wiper 31 passesout of Contact with the sheet and the guide 36 willbe moved away fromthe front edge thereof by the further travel of the cylinder 11 carryingthe roller 44 along the cam 45. When the grippers 12 open to transferthe sheet from the cylinder' 1]. to the cylinder 9, the guide 62 will bemoved out oi' the way by the rotation of the shaft 1 3 and the contactoi the members 66 and 68. In the arrange ment shown, the wiper 31 willcontact with the sheet more than once after positioning` it against thegage 36 but since the cylinder 11. is provided lwith a wiper abutmentonly at a point adjacent the gage 36, the sheet will not be disturbed bythese additional contacts. From the description just given, it will beseen that with my novel device, sheets may be presented to a carrier ata speed approximately that oif the carrier and with the head oi thesheet very accurately positioned. against a carried by said carrier,since this edge is held so that it cannot move up or down the gage whenbrought in contact therewith, this motion up and down having heretoforebeen one of the chief` sources ot error in positioning sheets. [t willalso be seen that at the instant in which the gaging taires place, therelative velocities of the sheet and `gage may be very high, so that asheet considerably out of square may be brought accurately in positionagainst both gages in the small traction of time in which the sheet isbeing presented to the gage. This high relative speed is accomplished bythe motion ot the gage 36 in a direction contrary to that of the sheetunder the control ot the wiper 31. By reason of the vertical adjustmentoi the gage 36 andthe use oit these gages as stops for the guides 62, Iam able to'provide a space between the member 60 and the guides 62 whichwill be proportioned to the thickness of the sheet to be gaged. Thisadjustment is materially assisted by the extension member 61 of themember 59, for it is possible to place a sheet of the paper or othermaterial to be gaged between this eX tenson61 and the gage 36 beforefastening the gage 36 in position by the screw 36 and thus iixing thespace between the guides 62 and the member 60 according to the thicknessof the sheet to be gaged..

y While I have shown the member 6() as mounted on the arm 37 andtherefore having a speed less than that of the periphery ot the cylinder11 at the time the wiper 31 cooperates therewith, it is obviouslypossible to mount this member 60 "on an arm independent oif the arm 37,in which case it may have the saine speed as the periphery ot the WhileI have shown the guides 62 as op-` pers 12 as the overguides in place ofthe guides 62. rlhis can be accomplished readily by shaping the cam 14so that the grippers 12 will be closed to the position of the guides 62shown in Fig. Q when the parts have arrived at the position shown inthat ligure and holding them in this position until their rguiding`function has been accomplished and then closing them on the sheet. Evenwhen the overguides 62'are used, the grippers 12 assist in positioningthe sheet, for it is obvious that the edge of the sheet between thesets'of guides 62 will be held up in place by the grippers 12 before thelatter close on it. It will also be obvious that the guides S2 cooperatewith the gripper abutments 15 as well as with the members 60, in thesense that such abutments are on one side of the sheet and the guides 60on the other, and so forni a sheet guideway between them, even thoughthe abutments 15 and the guides GO may not be in the same radial lineson the cylinder 11.

,lt is also obvious that many different forms ofmechanism for operatingthe arm Y37'1nay be provided and that the arm 37 may be replaced by anymovable support for the gage 36; I find the arrangement of the arm 37turning around the same center as the cylinder 11 particularly useful,since then the motion of the gage 36 is entirely in the path of theperipnery of the cylinder 11. For some purposes, it will be found usefulto adapt the mechanism for moving` the arm V37 so that the gagewillpractically stand still-in space While the sheet is being positionedagainst it. llVith the gage thus standing'still and the arm 37 turningon the center of the cylinder 11, the face of the gage remains inexactly the same position with relation to the sheet supports 17 and theperiphery of cylinder 11, precisely as if the gage were supportedexternally of the cylinder 11.

' While I have shown and described my feed cylinder 11 as one composedof rings, it is obvious that it may bevof any type and in the use of theWord cylinder, I do not wish to. be limited to the particular formshown.

It is also obvious that my device may be applied to any other form ofsheet carrier, such as a pair of traveling chains or belts.

lt is also possible to dispense with the use of the Wiper 31, in whichcase the sheet will be carried by the rollers 22 and pulleys 2O up tothe feeding point at the same speed as the surface of the cylinder 11.The bacle Ward motion of the gages 36 will then produce a relativemotion'between the gage'and the sheet to square the sheet and toregister it. Thilo l have shown and described a separate abutment memberGO with which the grippers 12 cooperate, it should be understood that ifthe cylinder 11 is one having a solid surface, such as an impressionsurface, no separate members would be necesthe front end of the solidsurface then acting as the abutments for the wiper 31 and the grippers12, and being the equivalent of the abutments 15 and 60.

While l have shown, as my preferred form, the pulleys 2O geared to movethe sheet at substantially the same speed as the periphery of thecylinder 11, l do not wish to be confined to this ratio, as it isobvious that, for many purposes, the pulleys may be geared to advancethe sheet faster, or even slower', than the periphery of the cylinder,and good register could be obtained, so long as there is a relativemotion between the edge of the sheet and the gages 3G toward each other.

The mechanism which I have shown pro- Yides a simple device for alteringthe amount of margin on the sheet or of shifting the gages to bring thesheets into register from a point remote from the feeding point andvhile the machine is in motion. An inspection of Fig. 3 will snow thatthe rotation of the shaft 50 will move the cam 15 toward and away fromthe side frame of the machine, according to the direction in which it isturned. llilith the parts in the position shown in Fig. 3, it is obviousthat the wedge -i-ll 'will have the motion produced by the tra-vel ofthe roller 44 from the lowest to the highest portion of the cam 45. Ifthe shaft 50 is turned so as to draw the cam L15 toward the side frame,the amount of motion will be determined by the travel of thc rollertfrom the position shown in Fig, where it is held by the stop pin 72, tothe highest point of the cam, which will then be much nearer the sideframe than is shown in Fig. 3. Consequently, the gage 3G, controlled bythe cam 45, will be moved a less distance toward the sheet or to theleft in Fig. 2, than it would be when the cam -15 is in the positionshown in Fig. 3, thus altering the margin of the sheet. The position ofthe cam 45, therefore, in relation to the side frame, de termines theamount of margin which thc sheet will have, the gage 3G being normallyout of gaging position and being moved into ga ging position by themechanism of Fig. 3. Since the shaft 50 and the mechanism forcontrolling it is duplicated on the opposite side of the machine, andthese duplicate mechanisms are connected by the shaft 5T, it is obviousthat the turning of the wheel M will serve to move both of the gages 86in the same direction and b v equal amounts. If it is desired to shiftone of the gages without shifting the other, the wheel 54; is

lll() pushed downward, thus disengaging the gears and 56 and then theWheel 58 or the Wheel 5a is turned, each wheel then controlling1 one ofthe `gages independently of the other.

It will be understood tlnit all of the parts olf my novel sheetpositioning device are adjustable crosswise oi the machine to bring thevarious ,franges and rollers into correct relation with a sl; eet oitany Width. lt Will also be understood that while l have shown speciiicarrangements for carrying out varions features oi my invention, I do notWish to be restricted to these i'orins nor to the combinations ot thevarious features of my invention which I have disclosed, since many oitthese features may be used separately and in various hinds oi machines.
